4-2. 【LD】,【LDI】,【OUT】
Mnemonic Function Format and Devices
LD
(LoaD)
Initial logic operation
contact type NO (Normally
Open)
Devices: X, Y, M, S, T, C, Dn.m,
FDn.m
LDI
(LoaD Inverse)
Initial logic operation
contact type NC (Normally
Closed)
M0
Devices: X, Y, M, S, T, C, Dn.m,
Dn.m F
OUT
(OUT)
Final logic operation type
drive coil
D
evices: X, Y, M, S, T, C, Dn.m,
FDn.m
r Setting bound of K Timer/Counte The actual set value
1ms timer 0.001~32.767 seconds
10ms timer 0.01~32.767 seconds
100ms timer
0.1~32.767 seconds
1~32,767
16 bits counter 1~32,767 Same as the left
32 bits cou ter 1~2,147,483,647 Same as the left n
z Connect the LD and LDI instructions directly to the left bus bar. Or use
them to define a new block of program when using ANB instruction.
z OUT instruction is the coil drive instruction for the output relay、
auxiliary relay、status、timer、counter. For the input relay, cannot use.
z Can not sequentially use parallel OUT command for many times.
z For the timer’s time coil or counter’s count coil, after using OUT
instruction, set constant K is necessary.
z For the constant K’s set bound、actual timer constant、program’s step
relative to OUT instruction(include the set value)
